Remark:
1,Betalent carbide keeps stock for standard size listed, ready to ship in most situations.
2,Size beyond this list can be customised as per drawing or sample.
3,Different grades carbide can be applied base on work piece character specially the hardness.
For milling workpiece of which hardness is HRC 60 to 65 degree, carbide grade BT60 is applied as raw material(ground carbide rod), BT45 has below physical characters:
| Grade | Co% | Grain Size | Density (g/cm) | Hardness(HRA) | TRS N/mm2 | Application |
| BT60 | 9 | 0.2 | 14.35 | 94.1 | 5000 | For cutting tools machining quenched materials (HRC60-65), hardwood and high polishing cutters. Finish machining 316L stainless steel. |
Ordinary 4 flute ball nose end mill has poor heat dissipation effect when it is used, so when it works in high intensity for a long time, a lot of heat will be generated, which will affect the service life of the ball nose end mill. Moreover, some metal chips remain in the chip removal groove of the 4 flute ball nose end mill during milling. And the outer spray coolant could not completely spray to the chip removal slot hence reduce the effect of the spray coolant. Betalent carbide improve this problem, we developed a high temperature resistant 4 flute ball nose end mill to overcome the shortcomings of ordinary 4 flute ball end mill.
